The Three-Dimensional Noncommutative Nonlinear Sigma Model in Superspace
H. O. Girotti, M. Gomes, A. Yu. Petrov +2
We study the superspace formulation of the noncommutative nonlinear supersymmetric O(N) invariant sigma-model in 2+1 dimensions. We prove that the model is renormalizable to all or…

The Noncommutative Supersymmetric Nonlinear Sigma Model
H. O. Girotti, M. Gomes, V. O. Rivelles +1
We show that the noncommutativity of space-time destroys the renormalizability of the 1/N expansion of the O(N) Gross-Neveu model. A similar statement holds for the noncommutative…
